Contains information/code for different card types

Structure of a repo:

• README.md - this file
• types - directory to keep all card types Each card-type should be presented in form:

1. Separate directory with card-type name
2. REAMDE.md file which explains the main purpose of type. Screenshots with examples and so on
3. example.json5 - example card, described according to the card type
4. validator.js - file, which should provide validation function, exported by default (in commonjs modules format), which should return true/false for incoming object. Better to use json-schema validation.
5. index.js - file, which converts incoming object (like from example.json5) to structure. Should provide the single function as default export (commonjs modules format).
